Bonneh's Illusion

HOW IT WORKS: Stare at a yellow dot in the animation. Eventually, one or two of the other yellow dots will disappear.

This illusion supposedly proves Professor Jack Pelligrew's theory that the brain is continually switching between the right and left hemispheres.

The theory of brain switching came about when Professor Pettigrew attempted to explain the odd optical behaviour of a fish known as the Sandlance.

The Sandlance's eyes are disconnected from each other's motion and unlike most animals, it's eyes can move independently of each other. It's eyes do not move simultaneously, only one eye moves at a time.

Professor Pettigrew theorised the reason for this sequential motion is that each eye is connected to only one hemisphere of the brain, right eye to the right hemisphere, left eye to the left hemisphere and when the brain switching occurs only one side of the brain at any one time has full control of the brain and hence body. In this case the side being switched to.

This also means that the eye connected to the side being switched to has the ability to or "right of way" to send signals to the necessary muscles in order for it to move.

i dont get it

Read the explanation in box to the right of the video. You'll need to click on the word, "more" to expand the explanation.

Basically, it works this way: Stare at a yellow dot in the animation. Eventually, one or two of the other yellow dots will disappear.

Apparently, it's evidence to support an important theory about the brain.

Woops misspelt the word, "explanation" in my video.

My "switch rate" actually explains a lot. I can make the surrounding dots disappear then reappear within about four seconds. I shit you not- I've noticed that when I'm in any kind of distress (extremely nauseous/injured/etc.), the pain reaches its climax then subsides for about four seconds and repeats the cycle. Really weird but probably worth thinking about...

THAT WAS AWESOME

[saturn20001]

OMG IT ACTUALLY WORKS !!!!!!!!

[RobertAaronPerry]

your stupid your supposed to stare in the middle of the dots and relax your eyes

[LtUnreal]

its much harder to make them disappear when looking at the bottom one, for me :|

also, even if they do disappear, it's only for about 1 second, for me :/

[OmegaWolf747]

The other two don't disappear, but they fade if I concentrate on one of them.

this really didnt need to be a 2 min video...

[SugarLoadedFTW]

You're probably self-consciously looking at those ones too to see if they ARE disappearing. Don't, lol.
